The Schneider Electric LP1D40004JW is a 4-pole contactor from the TeSys Deca family, rated for AC-1 60 A at 440 V with a 12 V DC coil. AC-1 covers resistive loads — heaters, lighting banks, non-inductive circuits — so the 60 A figure is the thermal current the main poles can carry continuously in that duty. For motor starting (AC-3), the switching capacity is lower; the utilisation category list includes AC-3 and AC-4, meaning this contactor is also specified for occasional motor switching, but the AC-1 number is the one that governs continuous current in a resistive circuit. Four poles give you the option to switch three phases plus a neutral, or two independent load circuits, in a single device. The 12 V DC coil draws from a control transformer or battery-backed supply — common in safety circuits or low-voltage control schemes where 24 V is the norm but 12 V legacy systems still run.
Mounts on either a DIN rail or a mounting plate — the plate/rail support covers both panel-build styles. IP2X means finger-safe against accidental contact with live parts, which is the minimum for a panel-mounted device behind a locked door.
Certified to IEC 60947-4-1 and EN 60947-4-1 (the contactor standard for motor starters and controllers), plus VDE 0660, JEM 1038, BS 5424, and NF C 63-110. That covers acceptance in European, Japanese, UK, and French markets. Operating temperature range is -40 to 60 °C, with derating above 60 °C up to 70 °C; storage from -60 to 80 °C.
